What does Sanitize PDF actually remove?

It neutralizes embedded JavaScript, OpenAction triggers, and Launch actions — the mechanisms most often used to hide unwanted behavior inside a PDF file.

Why would a normal PDF contain scripts or hidden actions?

Some PDFs use embedded scripts for legitimate interactive forms, but the same mechanism can hide tracking or malicious code — sanitizing removes it regardless of intent.

Does sanitizing remove visible content or formatting?

No. Sanitizing only strips hidden scripts and actions from the file structure; visible pages, text, and formatting are untouched.

Is this different from Edit Metadata?

Yes. Edit Metadata changes visible info tags like Title and Author. Sanitize PDF removes hidden, potentially harmful code — many people use the two together before sharing a sensitive document.

What is PDF Sanitization and Why Is It Critical?

A standard PDF document is far more than static text and graphics. Under the ISO 32000 specification, PDFs can encapsulate embedded executable JavaScript (/JS and /JavaScript object dictionaries), automated launch actions (/Launch), document-open triggers (/OpenAction and /AA), and external URI phone-home beacons. Malicious actors and automated telemetry tools frequently exploit these hooks to track readers or deliver exploits.

True Client-Side Script Neutralization in WebAssembly

PDFMinty provides true client-side PDF sanitization directly within your web browser. When you drop a document into this tool, our local parser traverses the indirect object table in browser memory, locating and stripping all active executable streams, malicious launch triggers, and hidden tracking metadata. The visible text, typography, high-resolution raster images, and vector artwork remain 100% intact and untouched.

Sanitization Checklist: What PDFMinty Strips

Embedded JavaScript: Neutralizes scripts that execute automatically upon opening or scrolling pages.
OpenAction & Additional Actions: Removes automated URL requests and external program launch triggers.
Hidden Form Traps: Disarms automated submit-form actions that transmit document interactions to remote servers.
Embedded Launch Keys: Eliminates system execution vectors without altering the visual page canvas.

Comprehensive Pre-Publication Workflow

For legal departments, healthcare providers, and investigative journalists, sanitization is the final essential step before public release. After sanitizing your document, you can also modify descriptive tags via our Edit PDF Metadata Tool or apply AES encryption using our Protect PDF Tool.
